4 Claims.

The present invention is applicable to roofs, skylights and like structures of roofing material such as glass, sheet metal, and material or that character, and the principal object of the in 5 vention is to provide for draining moisture of condensation on the inside of the roof structure to the outside thereof so that it may not drip or drop inward from the roof while excluding dust, dirt, wind and weather.

Stated generally, the invention comprises an inverted trough or channel strip of metal having staggered notches, openings or weep holes in its side walls, and a sinuous strip of fibrous or filtering material arranged in the trough to prevent filling or clogging of the weep holes by dust, dirt and the like blown by the wind against the roof structure and to exclude the weather.

The invention also comprises the improvements to be presently described and finally claimed.

In the following description reference will be made to the accompanying drawing forming part hereof and in which Figure 1 is a vertical sectional view, illustrating more or less diagrammatically, a roof structure and showing features of the invention in application thereto.

Fig. 2 is an edge view of a portion of the channel strip shown in Fig. l and also showing the staggered weep holes, and

Fig. 3 is a plan View looking upward in Fig. 1, and showing the sinuous strip of fibrous or like dust filtering or catching material.

Referring to th drawing, 1 represents an inverted sheet metal channel or inverted troughshaped section of metal. The side walls of the element 1 are provided with staggered notches, openings or weep holes 2. 3 is a sinuous strip of mineral wool or fibrous or filtering material,

and it is provided with a wire core 4 which, when present, holds it in sinuous form, as shown in the drawing. 5 and 6 are lapped roofing plates between the lapped portions of which the parts 1 and 3 are arranged as indicated in the drawing.

In use moisture of condensation travelling or flowing down on the inner face of the roofing plate 5 enters the interior of the channel strip 1 through the weep holes 2, and, passing by or through the strip 3, escapes through other weep holes 2 and flows to the outer face of the roofing plate 6. The staggered arrangement of the holes 2 prevents weather-wind, rain, snow and the like-from blowing directly through from the outside to the inside of the roof. The fibrous strip 3 opposes the passage of dust and also one form, as shown, prevents filling or clogging of the weep holes.

It will be obvious to those skilled in the art to which my invention relates that modifications may be made in detals of construction and arrangement and matters of mere form without departing from the spirit of the invention which is not limited to such matters or otherwise than the prior art and the appended claims may require.

I claim:

1. Means for interposition between the spaced and overlapped portions of roofing plates which comprise an inverted trough or channel strip of metal having notches or weep holes in its side walls, and a strip of fibrous filtering material arranged in the trough and spaced away from said notches or weep holes.

2. Means for interposition between the spaced and overlapped portions of roofing plates which comprise an inverted trough or channel strip of metal having staggered notches or weep holes in its side walls, and a sinuous strip of fibrous filtering material arranged in the trough and spaced away from said notches or weep holes.

3. Means for interposition between the spaced overlapped portions of roofing plates which comprise an inverted trough or channel strip of metal having staggered notches or weep holes in its side walls, and a strip of fibrous filtering material arranged in the trough and spaced away from said notches or weep holes.

4. Means for interposition between the spaced and overlapped portions of roofing plates, said means comprising in combination a trough or channel strip of metal of inverted U-shape in cross section having spaced parallel side walls and having staggered notches or weep holes in said side walls, and a sinuous strip of fibrous filtering material arranged in the trough and spaced away from said notches or weep holes.
